Changing a laptop battery is a relatively simple process. Typically, a new lithium Ion laptop battery will give satisfactory performance through approximately 500 charge-use-recharge cycles. This translates to approximately three years of working life with light-duty use.
Early laptops were run on standard AA size batteries. However, they consumed so much power that they could run on one set of batteries for only a few hours. The first commercial IBM-compatible Laptop computers are small and light enough to carry in a backpack and could be operated on a lead-acid batteries of the type used in automobiles.
The latest generations of batteries used in laptops, "smart batteries". This is due to the capacity of the battery, the user communication with the handset. Unfortunately, the definition of a "smart battery" is not universal, but varies between different manufacturers and regulators. Some manufacturers claim their batteries 'smart' becausetheir batteries incorporate a pre-programmed chip that sets the charger as per standard requirements. Most 'smart' battery chargers are controlled by the parameters of the chemical cells. Once the chemical cell has degraded, the laptop battery has to be changed. In some cases, the chemical part of the battery can be fully restored but the fuel gauge may become inaccurate or other data may get corrupted. In such cases, even though the digital readout becomes inaccurate due to malfunction, the battery will still fully charge and function normally for some time.
At the end of its working life, the reversible chemical processes inside a laptop battery degrades substantially. This leads to a state where the battery is unable to provide power to the laptop unless it is connected to the main 110 Volts supply through an adopter. This means that the laptop effectively becomes a desktop.
When the time comes to change the laptop Battery, it is better to buy a laptop battery replacement by the Agency, which has sold. You should also get the battery suppliers to replace the battery, as it would be more familiar with the process.
